The web page that Scott Ketelsen referred to recently (website and photo are no longer
there) actually has a picture of my
grandfather Dr. William H. Presnell surrounded by Ketelsen kids; he
was the doctor for a sizable chunk of the county and delivered many
Clinton Co. residents (older than about 35) when they were born. He
had a small doctor office in the town where my grandparents lived,
Charlotte (between Delmar and Goose Lake I think).
Thanks,
